Document Summary
Earth sciences are more than oil, gas, and mineral deposits. Take sedimentary core samples and carbon date them to learn about different time periods. National geographic investigation into maya skull at bottom of cave pit. Can use geographic information given from sedimentary landscapes left from tsunamis and used to date the fossils and information in the area. Paleoclimate studies from a lake core are used to understand the relationship between climate variability and food resources for native americans. Geological timescale is the foundation for all earth history which is categorized periods of earth evolution. Fossils helped play a role in the break up of different time scale divisions. Speciation and extinction events often mirror large scale earth events such as sea level change. Fossil record is biased towards oceanic environments as many of the ocean basins were connected allowing widespread colonization. William smith, made the map of the strata of england and wales.
